The purposes of this study were to develop a Minimal Insomnia Screening Scale for Korean adults (KMISS) and to evaluate psychometric properties and discriminant ability of the developed scale.
Data from a cross-sectional survey of 959 Korean adults were analyzed to develop the summated insomnia scale, which was evaluated in terms of reliability, validity, and discriminant ability by receiver operating characteristics (ROC) curve analysis.
Item-total correlations ranged between .71-.79 and Cronbach's α was .87. Adequate validity was also evident. ROC-curve analysis showed area under ROC was .87 (95% CI: .84-.90) and identified the optimal cut-off score as ≤ 20 (sensitivity, .83; specificity, .75; positive/negative predictive values, .40/.95). Using this cut-off score, the prevalence of insomnia in the study sample was 26.3% and most frequent among women and the oldest group.
Data supports the psychometric properties of KMISS as a possible insomnia screening instrument. KMISS also shows promise as a convenient ultra-short screening measure of insomnia for adults and epidemiological studies in community health care settings.
本研究旨在开发一种适用于韩国成年人的最小失眠筛查量表（KMISS），并评估所开发量表的心理测量特性和判别能力。
对959名韩国成年人的横断面调查数据进行分析，以开发累积失眠量表，并通过受试者工作特征（ROC）曲线分析对其信度、效度和判别能力进行评估。
项目与总分的相关性在0.71 - 0.79之间，克朗巴哈α系数为0.87。效度也足够明显。ROC曲线分析显示，ROC曲线下面积为0.87（95%CI：0.84 - 0.90），并确定最佳截断分数为≤20（敏感性，0.83；特异性，0.75；阳性/阴性预测值，0.40/0.95）。使用该截断分数，研究样本中失眠的患病率为26.3%，在女性和年龄最大的组中最为常见。
数据支持KMISS作为一种可能的失眠筛查工具的心理测量特性。KMISS也有望成为一种方便的成人失眠超短筛查措施，用于社区卫生保健环境中的流行病学研究。
